Hi raghu, According to my understanding the srcInfo of ARQ and the sourceAddress of SETUP are not related. Considering case ii, when you send a ARQ (after receiving SETUP from EP2) ,the srcInfo will be relevant to EP1 and not to EP2.
Correct me I'am wrong.

Hello everybody..
This is regarding the ARQ message.There are two instances at which an enpoint EP1 will send ARQ message to the Gatekeeper.
Case - 1: Needs to send SETUP message to EP2
Case - 2: Received SETUP message from EP2.
In both these case what will be the value for following Information elements:
destinationInfo, destCallSignalAddress, destExtraCallInfo, srcInfo, srcCallSignalAddress.
I belv these are related to the source and destnation of the Q.931 call. Typically in the above case
Case - 1: Source is EP1 and Destination is EP2. Case - 2: Source is EP2 and Destination is EP1
In the above case srcInfo is mandatory in ARQ while the corresponding related Information Element sourceAddress is optional in the case of SETUP message. Typically in the Case-2: if the EP2 had not provide the alias information, there is no way by which the EP1 can provide the info in ARQ. Pls correct me if Iam wrong on the above mentioned point.
Any help on the above highlighted point will be useful..
Thanks
Raghu
